Geranium plant named ‘Balcolcork’

ABSTRACT

A new and distinct cultivar of Geranium plant named ‘Balcolcork’, characterized by its cascading and mounded growth habit; freely basal branching habit; dark green-colored leaves with darker zonation pattern; and light red-colored double flowers.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Pelargonium peltatum cultivar ‘Balcolcork’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium peltatum, and hereinafter referred to by the name ‘Balcolcork’.

The new Geranium is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program was to develop new freely flowering Geraniums with attractive flower and foliage colors.

The new Geranium originated from a cross-pollination made by the Inventor of a proprietary Pelargonium peltatum selection identified as code number BFP-2175, not patented, as the female, or seed, parent with a proprietary Pelargonium peltatum selection identified as code number BFP-2022, not patented, as the male, or pollen, parent. The cultivar ‘Balcolcork’ was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Arroyo Grande, Calif., in 1999.

Asexual reproduction of the new cultivar by terminal cuttings taken at Arroyo Grande, Calif., since June, 2000, has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Balcolcork’. These characteristics in combination distinguish ‘Balcolcork’ as a new and distinct cultivar:

1. Cascading and mounded growth habit.

2. Freely basal branching habit.

3. Dark green-colored leaves with darker zonation pattern.

4. Light red-colored double flowers.

Plants of the new Geranium differ from plants of the parent selections primarily in flower color.

The new Geranium can be compared to the cultivar ‘Flair’, not patented. However, in side-by-side comparisons conducted in Arroyo Grande, Calif., plants of the new Geranium differed from plants of the cultivar ‘Flair’ in the following characteristics:

1. Plants of the new Geranium had shorter lateral branches with shorter internodes than plants of the cultivar ‘Flair’.

2. Leaves of plants of the new Geranium had a distinct zonation pattern whereas leaves of plants of the cultivar ‘Flair’ did not have a distinct zonation pattern.

3. Plants of the new Geranium had shorter peduncles and pedicels than plants of the cultivar ‘Flair’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Flower and foliage colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Geranium.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers of ‘Balcolcork’.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balcolcork’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown 10-cm pots in Arroyo Grande, Calif., under commercial practice in a polycarbonate-covered greenhouse with day temperatures about 20 to 22° C., night temperatures about 18 to 20° C. and light levels about 2,500 to 3,000 foot-candles. Plants used for the photographs and description were about 8 to 10 weeks from planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
